High oil prices spur EOR activity ///

High oil prices and declining reserves of light crude are serving as the incentive to extract as much oil from existing reservoirs as possible. In addition, there are renewed efforts, and considerable focus, on adapting recovery techniques to the production of heavy oil. In mature fields, enhanced oil recovery (EOR) techniques, such as carbon dioxide injection, waterflooding, polymer flooding, chemical treatment and gas lift, have increased production from older formations and are seeing success in heavy oil recovery.
